2 Claims.

This invention relates in general to a stove having a burner box forreceiving the gas burner which is shielded from the coal fiuessurrounding the oven and has more particular reference 5 to a baflleplate for improving the draft and the flue passage.

In a combination range having an oven separated from a gas burner box bya flue'from the re pot for heating the oven, the location of the lburner box top forms a rather deep pocket directly back of the fire boxwhich is detrimental to the draft of the range retarding the travel ofthe heating gases through the proper flue channels.

In order to overcome the effect of this pocket a l baille plate isprovided which extends as a continuation of the flue below the burnerbox and extends below the top of the stove so that all the heat from thefire box enters directly into this channel and there is no furtherinterference or retardation of the draft when the baiiie plate isinstalled.

An important object of the invention is therefore in the extension ofthe ilue for keeping the flue dimensions of proper size throughout theirpassage above the oven.

A further object of the invention is in protecting the top of the rangefrom becoming overheated which is frequently the case where the largepocket is provided directly back of the re box.

A still further object of the invention is in protecting the adjacentend of the burner box from becoming overheated by the direct heat fromthe fire box if permitted to strike the adjacent end of the burner boxwhich is usually finished in enamel and is easily destroyed by excessiveheat.

A still further object of the invention is in the provision of a baieplate shaped to conform to the flue passage and supported in placewithout engaging the range top but allowing suicient space below the topfor the circulation of heat under the lids of the range for cookingpurposes.

A still further object of the invention is in improving the performanceand efiiciency of the range by means of a baffle plate.

Other objects of the invention will appear hereinafter, the accompanyingdrawing illustrating a preferred embodiment of the invention.

In the drawing:

Fig. 1 is a plan view of a combination range with portions broken awayillustrating the invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Referring more particularly to the drawing, a

combination range is shown as having a iire box 5 in which a fire potand dumping grates 'I are conventionally represented with end walls 8and 9, a bottom It supported by the base I I and legs i2. Within therange is a transverse partition I3 forming the other wall of the firebox and an oven 5 having top, end and bottom walls I4, I5 and I 6respectively which is spaced below the burner box I 'I at the topforming a flue I8 leading from the top of the fire box over the top ofthe oven and downwardly at the end below the bottom to the bottom 10 ofthe discharge flue or stack I9 which carries the gases away. The top 2i!of the range has a conventional sectional cover, with lids 2I over there box, lids 22 over the burner box and lids 23 over a pocket 2d locatedbetween the upper end 15 of the fire box 5, the adjacent end of theburner box I'I and the top E4 of the oven. This pocket is an enlargementof the flue I8 and is detrimental to the draft by retarding the ow ofthe hot gases which must rst lill up this pocket so that 20 in effectthe pocket causes a swirl, drag or a partial vacuum in retarding thetravel of the gases about the oven.

Another effect of this pocket is unduly to heat the end of the burnerbox I'I adjacent thereto 25 and to unduly heat the top directly abovethe pocket.

In order to overcome the effect of this pocket 2li a bafe plate 25 isinserted within the pocket having a lip or offset 26 along the loweredge to 30 extend below the adjacent edge of the burner box I'I androunded upwardly at the opposite edge to extend adjacent but short ofthe top 2U as shown more clearly in Fig. 2, conforming also to the flueI8 at this point and' making it a continuation of 35 the flue betweenthe top of the oven and the bottom of the burner box I'I.

In order to hold this deector plate in position a support 2l is attachedto the underside of the bafie plate by a bolt 28 or other suitablefasten- 40 ing means and preferably has opposite legs engaging aprojection 29 cast in the top I4 of the oven and the other leg engagingthe lower end of an angle plate 30 set in between the top of the ovenand the upper edge of the partition 45 wall I3 which is held in place bya projection 3I at the top of the oven.

Either one or both ends of the bafe plate 25 may be rounded off asindicated at 32 in Fig. 1 or the baffle plate may be terminated short of50 the front or back wall of the range as therein shown so that any gasaccumulating above the baffle plate will find its way into the main flueof the range.

With this construction the objectionable space 55 or pocket iseliminated, the flue is made of substantially continuous size or uniformcross section from the top of the fire pot and sufficient space isafforded between the upper edge of the deflector plate and the top ofthe range for circulating suiicient heat under the lids 23 of the rangefor cooking purposes.

With this construction there is no danger of overheating either the lids23 or the end of the burner box l1 and there is no delay or retardationof the passage of the flue gases and the oven is heated more quickly andmore positively without loss of heat and, therefore, with greatereiiiciency.

While this bafle plate is described in connection with a range of thistype, it is obvious that a similar construction may be employed foreliminating iiue pockets of this kind wherever they may be located.

I claim:

1. In a stove the combination with a re box, a burner box and an ovenforming a pocket above the oven and between the burner box and the rebox with a ue of smaller size leading therefrom across the top of theoven, a stove top extending across the top of the pocket and a delectorplate extending from the lower adjacent edge of the burner box upwardlyacross the pocket toward the top of the fire box but terminating shortof the stove top to allow heating gases to reach the stove top above thetop of the deector plate.

2. In a combination range a fire box, a burner box and an oven, togetherforming a pocket between them and the top of the stove With a flueleading therefrom between the burner box and the oven, a baie plateextending from the lower edge of the burner box in said pocket upwardlytoward the upper edge of the fire box, the end of the plate terminatingshort of the side of the stove to allow any gases accumulating above theplate to find their way to the flue around the end of the plate.
